STORAGE-BA'JJTERYk PLATE.

Specification of Letters Batent.

Patented Feb. 25, 1908.

To all 'whom 'it may concern.'

Be it known that I, ALFRED O. TATE, a subject of the King of Great Britain, residing in the city of Toronto, Province of Ontario, county of York, and Dominion of Canada, have made a new and useful Invention in Storage-Battery Plates, of which the followin isa specification.

ily invention relates particularly to storage battery plates of the bifunctional type,

such as are disclosed in prior applications filed by me in the U. S. Patent Office, bearing respectively No. 289,796, filed Dec. lst, 1905 and No. 382,119-, filed July 3rd, 1907, and it hasffor its objects, first, to provide a plate of this nature which will withstand ve severe usage without damage. Secon to provide a plate of this nature in which the -ariode and cathode strips shall be rigidly sustained at all times so that their mechanical and electrical relations shall not be materially varied in use. Third, to provide a plate of this nature in which the anode and cathode strips shall be separated from each other by well defined spaces' and the active material applied thereto on their opposite faces and in such manner that the entire side orlateral faces of the electrode shall be practically perfect planes so that the active material may be effectively inclosed Within the face of the plate and practical results of an important nature obtained. Fourth, to provide a plate of this nature in which the supportin base of the anode and cathode strips shalll e practically rigid and the strips secured in grooves therein with a fixed or definite relation to each other. Fifth, to provide a plate of this nature in which the anode and cathode strips shall be supported by and located in definite relation to each other with the active material applied thereto, and to further provide means for maintaining the same in a fixed or definite relation to said strips.

My invention will be fully understood by referring to the'afrt-,ompanying drawings, in

which, y

Figure 1 is a part side elevational sectional View of my novel bifunctional part stora rigid non-conducting plate seen looking thereat from the bottom toward the top of the drawings in the direction of the arrows. Fig. 2 is a transverse sectional view taken through Fig. 1 on the line'2-2 and as seen looking thereat from the bottom toward the top of the drawings in the direction ofthe arrows.

The bifunctional lates disclosed in the before-mentioned app ications embody a series of thin narrow interleaved anode and cathode strips, the anode strips being connected at one end to a conducting bar or rod and the cathode strips being similarly connected at the other end, said strips being separated by thininsulatin media and all bound together by binding blocks and nuts secured upon the ends of the aforesaid bars or rods, the action of the electrolyte being through the insulating material upon the lateral face's of the plate.

The present improvement is designed 4to produce a bifunctional storage battery plate which shall be simpler in construction and of a more rigid nature, in that the anode and cathode strips are located in pairs, side by rigid non-conducting base or support and said anode and cathode strips are connected one set at one end to a common conductor and the other set at the other end to a similar conductor, after which the active material is applied to the faces of said anode and cathode strips and both faces of the entire electrede covered by porous insulating media held in place by any referred means.

Referring now to t e drawings in detail for a description of the invention, such as will enable others skilled in the art to construct and use the same, b represents the supporting base made preferably of hard rubber, treated vegetable fiber, marble, or any well known insulatingmaterial which will withstand pro er i usage and will not be acted upon by the e ectrol te.l This base is grooved or channeled -in t e direction of its len th on its opposite faces, after which the ano e strips c, a, a, are located in each alternate pair of grooves on the opposite faces thereof and secured 1n any preferred-manner directly thereto. The upl' v instance at definite distances from each the right of Fig. l by a plus mark. 'lhe lower or loop ends ofthe cathode strips c, c, c, g

are siinilaily secured in the alternate grooves or channels from the bottom and are atminus mark. The active material, such red lead or any of the Well known equivalent substances, is then firmly packed in. place in the grooves or channels against the outer faces of the anode and cathode stripson both sides, until said grooves or channels are filled and the electrode plate assumes a plane survface on each face the adjoining edges of the anode and catho, e strips and the active material packedtl'iereon other throughout both faces.

p represents one or more (preferably of i four) plates of porous material, such as kaof lin, the same constituting means for protecting the opposite faces of the electrode and for l preventingl the active material from falling out of the'supporting grooves or channels. s represents flexible strips, preferably of rubber, for maintaining these platesin position against the faces of the electrode.

I do not limit my improvement to the special structure illustrated in the accompanying drawings, as a number of the features thereof might be materially departed 'from and still come within the scope of my claims hereinafter, the generic'feature of myinvention lying in the' provision of a bifunctional storage battery plate having a rigid frame or support for interelated anode and cathode strips secured thereto and in such manner that they always maintain a definite relation toward each other when in'iuse, the

eing located4 in each a strips located in said grooves in definite or fixed relation to each other, substantially as described.

2. .fl-bilunr-,tional storage battery plateJJ embracing a rigid base and a series of alternately disposed anode and cathode stri s tached in like manner directly to a common conductor indicated on the left Fig. v1 by a 1 a, a, a, through definite or fixed distances of insulation to and through corresponding i embracing a base or support grooved on its opposite faces anode and cathode strips and pairs of cathode strips similarly rigidly fixed,

so that the entire electrode has a permanent panying drawings for maintaining the active g material in place, as this feature may be varied by many well known mechanical devices, any of which will permit the fiee acl cess of the electrolyte to the active material.

vided with means on Vits opposite faces for sustaining alternately disposed anode and cathode strips in a fixed relation to each other, substantially as described.

4. A bifunctional storage battery-plate, embracing a rigid insulating base plate, having closely related grooves or channelsonits opposite faces, and alternately disposel'sets of anode and cathode strips ocatedirsaid grooves, substantially'as described. i.

grooved or channeled on'its opposite faces;

alternately disposed anode and cathode j strips locatedl in said grooves; the anode strips being connected at one end to a common conductor and the-cathode stripssimilarly connected to a like conductor, substantially as described. v

7. A bifunctional storage battery plate, embracing an insulating base plate provided with means on its opposite faces for sustaining or supporting alternately disposed anode and cathode strips and adapted to support active material about said strips, substantially as described.

6. A .bifunctional storage battery plate, embracing an insulating baseplate grooved or channeled on its-opposite faces; alternately disposed anode and cathode rstrips and active material supportedin said grooves or channels; in combination `with means for preventing the active material from falling out, substantially as described.

8. A bifunctional storage battery plate,

and liquid conveying protecting means se'- cured to the plate for preventing the active material from falling out, substantially as Having thus described my invention what described.
